Bere Island
Bere Island is a small, inhabited island located in Bantry Bay off the Beara Peninsula in County Cork, in the southwest of Ireland. It sits at the mouth of the bay, sheltered by the dramatic mountains of the peninsula to the north and the rugged uplands of the Mizen Peninsula to the south. Covering approximately 18 square kilometres, the island is home to a small permanent community of around 200 people, and it draws visitors seeking an authentic, unhurried slice of Irish island life, rich in military history, wild scenery, and a palpable sense of being removed from the mainland world. Despite its modest size, Bere Island carries an outsized historical importance and a landscape of considerable beauty.
The island's history is deeply intertwined with British military strategy. For much of the 19th and early 20th centuries, Bere Island was a significant Imperial naval station, with Berehaven Harbour — the sheltered deep-water sound between the island and the mainland — regarded as one of the finest natural anchorages in the British Isles. The Royal Navy maintained fortifications, signal stations, and garrisons here, most notably the Lawrence Cove base and the two martello-style gun batteries known as the Rerrin Battery and Ardnakinna Battery, the latter guarding the western entrance to the harbour. During World War One, the anchorage served as a base for convoys crossing the North Atlantic. Following Irish independence in 1922, Bere Island was retained by Britain as one of the Treaty Ports under the Anglo-Irish Treaty, a contentious arrangement that was only resolved in 1938 when the Irish Free State regained control of the port facilities under the Anglo-Irish Trade Agreement — a move that had major strategic implications during World War Two, as Ireland's neutrality meant the Allies lost access to an invaluable Atlantic harbour.
The landscape of Bere Island is a compelling mixture of open bog, farmland, rocky headlands, and rugged hills rising to just over 200 metres at Knockanallig. Walking across the island, one quickly notices the relative fertility of the lower ground compared to the windswept heights, where heather and coarse grasses dominate. The island's roads are narrow and largely car-free in feel, lending a quiet rhythm to any walk or cycle around the perimeter. The south-facing slopes enjoy surprisingly mild conditions thanks to the warming influence of the Atlantic, and the hedgerows can be lush and green even in winter. Standing at Ardnakinna Point on the western tip, visitors are met with wide, breathtaking views across the open Atlantic and back toward the mountains of the Beara, the silence broken only by wind, seabirds, and the low hiss of the sea.
The military heritage is preserved in a genuinely fascinating way. The remains of gun emplacements, observation posts, barrack buildings, and stores from both the British period and subsequent Irish Army use are scattered across the island, many accessible on foot. The Bere Island Heritage Centre, based in the old schoolhouse at Rerrin village, tells the story of island life and the military legacy with local charm and considerable depth. The cemetery at Rerrin contains the graves of soldiers from multiple nations, including a British military section and the grave of a German sailor washed ashore during one of the World Wars, a small detail that quietly encapsulates the island's role as a crossroads of Atlantic history.
The surrounding area, viewed from the island's heights, is spectacular. To the north lies the Beara Peninsula with its quartzite and sandstone ridgeline rising steeply — the Slieve Miskish and Caha Mountains form a dramatic backdrop. The town of Castletownbere on the mainland is clearly visible and remains the main point of connection. Bantry Bay stretches away to the east, broad and blue, while Dursey Island, accessible via Ireland's only inhabited cable car, sits just a few kilometres to the west. The sea between the island and the mainland is often busy with fishing trawlers out of Castletownbere, which is one of Ireland's largest fishing ports, adding movement and life to the view.
Visiting Bere Island is straightforward. A regular ferry service operates from Pontoon Pier in Castletownbere, with the crossing taking approximately 10 to 15 minutes. A second ferry service runs from Lonehort Pier on the eastern end of the island, offering another access option. There are no large hotels, though self-catering accommodation and bed and breakfast options are available on the island. Bicycles can be hired, which is arguably the best way to explore the island's roads and tracks. The island is particularly pleasant to visit between May and September, when the days are long and the wildflowers are in bloom, though the winter has its own austere appeal. Visitors should come prepared for changing weather, as the exposed Atlantic position means conditions can shift quickly.
Among the lesser-known stories of the island is the remarkable fact that during the Irish Government's takeover of the Treaty Ports in 1938, the handover on Bere Island was conducted with relatively little ceremony, despite the enormous strategic significance of the moment — a quiet end to a colonial chapter that had profound consequences for the coming world war. Local tradition also holds strong on the island, with Irish still spoken by some older residents and the community maintaining a distinct identity shaped by generations of relative isolation and self-reliance. The island has also become something of a quiet haven for artists and writers in recent decades, drawn by its light, its silence, and the almost theatrical quality of its ever-changing skies above Bantry Bay.
